include the FCS, and use it for the Daintree SNA file format. While we're at it, explicitly check to make sure the purported packet length gives it at least one byte of packet data, and fix some print formats to use %u for unsigned values. svn path=/trunk/; revision=33678

/* Encapsulation types. Choose names that truly reflect
|
|
* what is contained in the packet trace file.
|
|
*
|
|
* WTAP_ENCAP_PER_PACKET is a value passed to "wtap_dump_open()" or
|
|
* "wtap_dump_fd_open()" to indicate that there is no single encapsulation
|
|
* type for all packets in the file; this may cause those routines to
|
|
* fail if the capture file format being written can't support that.
|
|
* It's also returned by "wtap_file_encap()" for capture files that
|
|
* don't have a single encapsulation type for all packets in the file.
|
|
*
|
|
* WTAP_ENCAP_UNKNOWN is returned by "wtap_pcap_encap_to_wtap_encap()"
|
|
* if it's handed an unknown encapsulation.
|
|
*
|
|
* WTAP_ENCAP_FDDI_BITSWAPPED is for FDDI captures on systems where the
|
|
* MAC addresses you get from the hardware are bit-swapped. Ideally,
|
|
* the driver would tell us that, but I know of none that do, so, for
|
|
* now, we base it on the machine on which we're *reading* the
|
|
* capture, rather than on the machine on which the capture was taken
|
|
* (they're probably likely to be the same). We assume that they're
|
|
* bit-swapped on everything except for systems running Ultrix, Alpha
|
|
* systems, and BSD/OS systems (that's what "tcpdump" does; I guess
|
|
* Digital decided to bit-swap addresses in the hardware or in the
|
|
* driver, and I guess BSDI bit-swapped them in the driver, given that
|
|
* BSD/OS generally runs on Boring Old PC's). If we create a wiretap
|
|
* save file format, we'd use the WTAP_ENCAP values to flag the
|
|
* encapsulation of a packet, so there we'd at least be able to base
|
|
* it on the machine on which the capture was taken.
|
|
*
|
|
* WTAP_ENCAP_LINUX_ATM_CLIP is the encapsulation you get with the
|
|
* ATM on Linux code from <http://linux-atm.sourceforge.net/>;
|
|
* that code adds a DLT_ATM_CLIP DLT_ code of 19, and that
|
|
* encapsulation isn't the same as the DLT_ATM_RFC1483 encapsulation
|
|
* presumably used on some BSD systems, which we turn into
|
|
* WTAP_ENCAP_ATM_RFC1483.
|
|
*
|
|
* WTAP_ENCAP_NULL corresponds to DLT_NULL from "libpcap". This
|
|
* corresponds to
|
|
*
|
|
* 1) PPP-over-HDLC encapsulation, at least with some versions
|
|
* of ISDN4BSD (but not the current ones, it appears, unless
|
|
* I've missed something);
|
|
*
|
|
* 2) a 4-byte header containing the AF_ address family, in
|
|
* the byte order of the machine that saved the capture,
|
|
* for the packet, as used on many BSD systems for the
|
|
* loopback device and some other devices, or a 4-byte header
|
|
* containing the AF_ address family in network byte order,
|
|
* as used on recent OpenBSD systems for the loopback device;
|
|
*
|
|
* 3) a 4-byte header containing 2 octets of 0 and an Ethernet
|
|
* type in the byte order from an Ethernet header, that being
|
|
* what older versions of "libpcap" on Linux turn the Ethernet
|
|
* header for loopback interfaces into (0.6.0 and later versions
|
|
* leave the Ethernet header alone and make it DLT_EN10MB). */
